Reproduction Preferences Additional InformationReproductive data concerning Magelona mirabilis is scarce (Fiege et al., 2000). The data that is available suggests that the reproductive period in Magelona mirabilis varies with geographic location and the breeding season of many polychaetes is known to vary with latitude. Fiege et al. (2000) reported males with sperm masses in St. Andrews, Scotland, in March and females with eggs in Berwick-upon-Tweed in March whilst egg bearing females in Lancieux, France, were recorded in May.
It is generally agreed that Magelona mirabilis displays characteristics typical of an r-selected species, i.e. rapid reproduction, short life span and high dispersal potential (Krönke, 1990; Niermann et al., 1990), and is characteristic of shallow, disturbed, non-successional habitats (M. Kendall, pers. comm.).
